DISPENSING APPARATUS.

Application mea may 13, 1907. semi no. 373,205.

To all whom it may concern: Be it known that I, Mansn, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Dispensing A paratus, of whlch the following is a speci cation, reference being had therein to the accompanying drawings.

This invention relates to improvements in sodal fountains and its object is to provide a device so constructed that a measured quantity of syrup and soda water may be drawn by one movement of a single lever, the etfervescent liquid being delivered in a comparatively large and then in a small stream to give the desired foaming, anda further object `is to provide a simple and compact construction embodying -cert-ain other new anduseful features in the construction, arrangement and combination of' parts, all as hereinafter more fully described, reference being had 'to theaccompanying drawings in whieh- Figure 1 is a vertical sectional view of a device embodying the invent-ion; Fig: 2 is a section at. right angles to that of *ig. 1, parts being shown-in elevation; Fig. 3 a sectional detail of the head of the faucet showing the opposite side of the same to that shown in Fig. 1; Fig. 4 is an enlarged sectional detail of one end of the soda measuring receptacle; and Fig. 5 a cross section of the same, showing the face of the partition.

1 is a suitable supporting table having an opening through which projects a vertical tube 2 secured therein by being externally screw-threaded and provided with a nut 3 on its lower end engaging the under side of the table. and extending upward through a hollow finishing column 4 formed of onyx or other suitable material engaged at its upper end by a faucet head or casing 5 screwed upon the upper end of the tube 2. This faucet casing is provided with a laterally extending discharge spout 6 which is separated at its inner end from the chamber of the casing by a wall 7 and the open ends of the casing or head are closed by screwcaps 8 and 9. The upper end of the tube 2- which opens into the faucet casing is closed by a disk or diaphragm 10 clamped between the end of said tube and a shoulder 11 formed on the casing and thus said casing or head forms a closed. chamber. Within ROBERT GEORGE this chamber at a short distance from the ca 8 is secured a disk 12 having an axial in et opening which communicates with an inlet tube 13 leading thereto and secured to the inner side of said disk. This tube extends downward through the diaphragm 10 and out of the lower end of the tube 2 of the supporting column. A large and a small discharge opening are also provided in said fixed disk 12 at a ousta-nce from the center opening and leading from the large opening at the inner side of the disk is a large discharge. tube 14 with its opposite end extending through the wall 7 into the spout a short distance, and a small discharge tube 15 leads from the small opening-in the disk through the wall and outward in the spout to near the discharge end thereof.

Engaging the outer surface of the disk- 12 is a leather facing 16 having holes to correspond with the openings in the disk and engaging this facing is a rotary valve member 17 having an axial bore opening into the inner end of the axial bore and adapted to register at its outer end with the discharge openings inthe disk as the valve is turned and form a duct 18 in the valve to conduct the fluid entering through the inlet tube 13 to one or the other ofthe discharge: tubes 14 and 15. A stem 19 having a transverse slot in its inner end to receive a rib 20 on the valve member, extends through an axial opening in the cap 8 and to its outer end is keyed an operating lever 21 by means of which the valve is turned. A screw threaded axial hole is provided in the stem 19 to receive an adjusting screw 22 which engages the rib 2O on the valve at its inner end and is provided with a head on its outer end by means of which it may be turned inward aga-inst the rib to force the valve toward its seat on the disk and preventv leakage.

Extending vertically in the axis of the column 4 and through the diaphragm 10 which forms a bearing therefor, is a hollow plunger rod 23 having a head 24 on its upper end within the chamber of the faucet casing 5 formed with a laterally extending tubular portion 25 communicating with the upper end of the tubular plunger and projecting through a slot 26 in the wall 7 to discharge into the spout 6. The plungerv rod is move-d up and down by providing a horizontal slot 27 in the head 24 which slot is engaged by apiir 28. on a revoluble disk 29 which turns Specification of Letters Patent. Patented Jan. 10, 1911;,

in the casing adjacent to the cap 9 and has a stem 30 projecting through the cap to which stem a lever 3l is keyed. The pin 28 being set 'to one side of the axis of the disk, when said disk is turned by means of its lever 31 the pin will travel about said axis and force the plunger rodby its engagement withthe slot in the head, up and down.

The two levers 21 and 31 are curved toward each other in the form of a bail embracing the casing and their ends are united by a detachable handle 32 having an internally screw-threaded socket 33 to receive a screw-threaded stem 34 made in halves, one half upon each lever. v

Below the table 1 is a receptacle 35 having a detachable head 36 and a fixed partition 37 at a short distance from this head.

In the axis of the partition is a hole 38 and an inlet passage' 39 and a discharge passage 40 each extend into the partition from its y edge and open through the side of the partition at the same distance from its axis. The discharge passage communicates at its outer end with the tube 13 and into the outer end of the intake passage a tube 41 is connected, its olpposite end being connectled to any suitab e supply of soda water under pressure. A disk valve 42 is provided in the receptacle between the head 36 and partition and this disk is formed with a y passage 43, one end of which opens at its axis to register with the hole 38 and the opposite end opens through its' side in position to register with'either the -passage 39 or 40 when the valve is turned. A stem 44 on the valve disk extends outward through a stuiiing box on the head and on its projecting end is secured a lever 45 engaging between two pins 46 extending laterally from the side of the plunger rod 23 so that when said rod is raised or lowered the valve 42 will be turned.

' Secured in an opening inthe table 1, is a metal cup 47 formed with an inwardly projecting ledge'48 to support the lower end of a glass cylinder 49 which ts within the cup and is held therein with a acking ring between its lower end and t e ledge, by an axial rod 50 detachably secured at its upper end by a cap 51 resting upon the upper end of the cylinder and at its lower end en aginga screw-threaded aperture in the hu of a spider formed in the cap. The lower end of the cup is formed with a lateral extension 52 terminating in a downwardly projecting -A cylindrical portion 53 closed by a screw-cap downwardly c osing valve 57 controls the admission of Huid to the lower end of the tubu- -the handle is attached, is moved downward lar plunger rod which opens through said piston.

In operation, the glass receptacle or stand pipe 49 is filled with lavoring` syrup and the syrup, filling the laterally extending lower end of the standpipe flows freely through the valves 56 into the c linder below t e piston. The handle 32 being in the position shown inthe drawings, the piston is held by the pin 28 at the upper end of its stroke and the valve 12 is turned so that'its passage 18 does not register with either or the discharge tubes, thus cuttin ofi' the soda water supp y in this position o the parts the Valve 42 1s turned so that the supply tube 41 is in communication with the measuring chamber which is thus filled under pressure. As f the operator brin s the handle 32 forward, the pin 28 carrie by the disk 29 to which forcing the plunger rod and its piston 55 down. The valves 56 come to their seats upon downward movement of the piston" and prevent the syrup which is trapped below the piston from assing back therethrough and thus it is orced past the valve 57, up the hollow plunger rod, and out ofv the nozzle 25 into the'spout- 6, the valve 57 preventing the syrup in the rod from falling to the level of that inthe standpipe after each o eration. Slight downward movement of the plunger rod turns the valve 42 and cuts off the communication between the supply tube 41 and the receptacle and further movement turns the valve so that the duct 43 registers with the passage 40 a portion of which is formed in the face of the wall concentric with the axis so that the tube 13 is in communication with the receptacle during the remainder of the 'throw of the valve.

The handle is moved some distance from the position in which it is shown before the duct 18 in the valve 17 registers with the rtube 14 and soda permitted to escape, and 110 a slight further movement cuts oii' the stream thrown by said tube 14 and at the end of the throw the duct registers with the tube 15 which discharges a very fine stream to cause the desired foaming.

The stroke of 'the piston 55 determines the quantity of syrup and the size of the Ineasuring receptacle' determines the amount of soda water which will be delivered, and by the turning of the one handle, these ingredients are delivered and mixed in the proper manner.
